Eravikulam National Park is a 97 km2national park located along the Western Ghats in the Idukki district of Kerala in India, between 10º05'N – 10º20'N latitude and 77º0'E – 77º10'E longitude. See:map.It is the first national park in kerala.

The main body of the park consists of a high rolling hill plateau with a base elevation of about 2,000 m. The terrain consists of high altitude grasslands interspersed with sholas. Anamudi, 2,695 meters, the highest peak in India south of the Himalayas is inside this park. Many perennial streams criss-cross the park. They merge to form tributaries of the Periyar river in the west and of the Cauvery River in the east. See:.[4]Lakkom Water falls is in this region.

A new bright reddish-orange-coloured frog with multiple glands and extremely short limbs has been discovered in the Eravikulam National Park. The newly discovered species is restricted to less than three km2 on the peak of Anamudi and deserves immediate conservation priority, scientists S.D. Biju of Delhi University and Franky Bossuyt of the Free University of Brussels said in Current Science. The frog has been assigned the name Raorchestes resplendens.[7] This frog, as compared to all other members of the genus, has multiple prominent glandular swellings: laterally behind the eyes, on the side of the dorsum, on the anterior side of the vent, on the dorsal side of the forearms and shanks, and on the posterior side of tarsus and metatarsus. Additional distinguishing characteristics include the colour of the iris (which is bright red), and extremely short legs.[8]

Three major types of plant communities are found in the Park – grasslands, shrublands and forests. The terrain above 2000m is covered primarily by grasslands. However, there are numerous small patches of forests in hollows and gullies in these areas. The deeper valleys are extensively forested. Shrublands predominate along the bases of the cliffs and interspersed in rocky slab areas. The antibacterial Eupatorium glandulosum is found here.

Prior to 1971, the area was managed as a game preserve by the Kanan Devan Hills Produce Company. The government of Kerala resumed control in 1971 (Kannan Devan Hill Produce (Resumption of lands) Act, 1971), and declared the Eravikulam-Rajamala Wildlife Sanctuary in 1975 to protect the habitat of the endangered Nilgiri tahr. It became a National Park in 1978.[9]
